This is top quality Imperial Topaz from Ouro Preto, Brazil, the only locality on earth where true Imperial Topaz is mined. Fantastic Apricot color. Strong orangy red. There is a ton of irradiated brown Topaz being marketed as Imperial Topaz. But true Imperial Topaz can be distinguished by two factors. First, it doesn't have any brown or champagne color. Second, the refractive index is slightly higher than common Topaz. Genuine Imperial Topaz of high quality often sells for $1000 per carat at retail. Wholesale is $500 per carat. We're asking only $250 per carat. This stone comes with the 16 page appraisal dossier from 1984.
